Talking Biotech #227 - Anti CRISPRs

-

The arms race between bacteria and the viruses that infect them brought the Cas9 and similar editing systems.  These enzymes are essentially a bacterial immune system, and now are being exploited as important tools in genetic engineering.  To counter the bacteria response viruses produce inhibitors of the Cas enzymes. Dr. Joseph Bondy-Denomy is a professor at the University of California San Francisco that studies these inhibitors.  He discusses their discovery and potential applications.

Film Review: The Need to Grow

-

The recurring ads on Facebook pulled at me to watch The Need to Grow , a documentary film about food and farming.  As someone connected with these areas professionally and personally, I thought it would be worth a watch.  Here is a review. First the good things.  The film is nicely shot and well written.  The majority of the work builds on themes such as nutritious diets healthy soils, and efficient energy. Those are the central underlying values of the film, and ones that I wholly endorse.  However, where the film falls apart is in its approaches to achieve those end points.  Two of the "experts" recruited for the film are none other than Jeffrey Smith and Vandana Shiva, two people with little training in science or farming (and no, Vandana Shiva is not a physicist as the film claims).  The narrator is actress Rosario Dawson, who early in the film makes the proclamation, "Agriculture is the most destructive human activity on the planet." It is clear where t

Food Babe Visits My University

-

It was 6:30 pm in the lab and I was just thinking about the last things I'd need to get done before I could go home.  Typical night.  Usually I'm riding home about 7 pm, but an email popped up asking me if I was going to go watch the Food Babe.  A click on a link would take me to the note on a UF Dean for Students Good Food Revolution Events website.  Vani Hari would be spreading her corrupt message of bogus science and abject food terrorism here at the University of Florida. Oh joy. There's something that dies inside when you are a faculty member that works hard to teach about food, farming and science, and your own university brings in a crackpot to unravel all of the information you have brought to students. She might have started from honest roots.  Her story says she was duped by an organic yogurt stand (join the club) into buying taro toppings that were filled with artificial, non-organic colors.  She realized that she could use social media to coalesce

Glyphosate, A.I. and Spreading Disinformation

-

 Here's a great example of how bad reporting and the war on glyphosate play hand-in-hand.  I don't know anything about the reporter, Stacey Scott at Gillett News (Gillett is a town of 32,000 in Wyoming), but the headline she/it (they use A.I. generated graphics, Stacey Scott might be an A.I. too-- no Twitter or online presence) generated has the potential to misinform.  The Agriculture Department?  You mean the USDA?   No. You mean some other major government regulatory agency? No. Some respected international agency?  No. Then who "warns" ?  It was the government of Amritsar.  What? Yes. Amritsar, a relatively small town/region by India standards. It's a major metropolitan hub in the northwest, not far from the Pakistan border. They have some agriculture there, mostly rice, palm oil, sugar cane and maize, apparently a lot of Basmati rice which is exported from small-holder farms. According to Scott's article, glyphosate is "a chemical known to cause canc
